Abstract
The effects of mineral pretreatment, ionic strength, pretreatment temperature, and cationic collector type on the flotation characteristics of quartz and magnetite were investigated. The extent of crushing prior to pretreatment had a significant influence on quartz flotation recovery from approximately pH 2 to pH 8. Alkyl amine collector chain length and the presence of one or two functional amino groups were critical parameters related to ionic strength. Increasing the pretreatment temperature had a slight depressing effect on quartz and magnetite flotation recoveries. In most cases, n-dodecyl-1, 3-diaminopropane was a superior flotation collector to n-dodecylamine for the recovery of quartz and magnetite.

The effects of size and grinding on the flotation of quartz
Gorman, Mark G. (University of Nevada, Reno, 1988)The effect of particle size and shape was studied in the quartz and n-dodecylamine flotation system through the use of sized quartz and glass beads. In addition, the degree of flocculation of the floated material is compared ... -

The use of amphoteric surfactants as flotation collectors
Schroeder, Charles Warren (University of Nevada, Reno, 1970)Amphoteric collectors may be of considerable interest in the area of froth flotation because they combine in the same molecule positive and negative functional groups. Such structure in a collector molecule would indicate ...
